    • PROBLEM TO BE SOLVED: To provide a method for economically producing an amorphous carbon particle which has high purity by eliminating metal components from the combustion ash of petroleum cokes, has no metal elution, is excellent in rigidity and strength, and has extremely small specific surface area and pore volume.
      SOLUTION: The production method for the amorphous carbon particle includes the processes of (1) humidifying the combustion ash of petroleum coke, (2) extracting metals in the combustion ash by adding an acidic water, heating and agitating, (3) separating an insoluble carbon from the metals dissolved in the acidic water in the process (2) and (4) drying and pulverizing the carbon separated in the process (3). The resultant amorphous carbon particle is characterized in that the cross-sectional surface is non-circular, the mass reduction rate after 60 min is
    • 待解决的问题:提供一种通过从石油焦炭的燃烧灰中除去金属成分而经济地制造具有高纯度的无定形碳颗粒的方法,没有金属洗脱,刚性和强度优异,并且具有极高的 小比表面积和孔体积。 解决方案:无定形碳粒子的制造方法包括(1)加湿石油焦炭的燃烧灰,(2)通过加入酸性水,加热搅拌,在燃烧灰中提取金属,(3) 在方法(2)和(4)中分离溶解在酸性水中的金属的不溶性碳,(4)干燥和粉碎在方法(3)中分离的碳。 所得无定形碳颗粒的特征在于横截面为非圆形,在保持温度为500℃的空气存在下,60分钟后的质量减少率<30%,平均粒径为1 -50微米。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a production method by which a tetravalent vanadyl sulfate aqueous solution of high purity in which the concentration of tetravalent vanadyl is high and the containing ratio of impurity metal ions can be suppressed, and which is usable as the raw material for an electrolytic solution of a vanadium redox flow battery, can suitably be obtained also in industrial mass-production.
      SOLUTION: The method of producing tetravalent vanadyl sulfate aqueous solution comprises: a stage (a) where salicylic acid or the aqueous solution thereof is added to a tetravalent vanadyl-containing sulfuric acid aqueous solution; a stage (b) where the pH of the acid solution prepared in the stage (a) is regulated to 3 to 7 with alkali, and the salicylic acid compound of vanadium is precipitated so as to be recovered; a stage (c) where the precipitates obtained in the stage (b) are brought into contact with a sulfuric acid solution to dissolve the vanadium; and a stage (d) where the salicylic acid is separated from the solution obtained in the stage (c).
